When a user logs in, the PM_USER_SESSION table size is now checked. If it has over 1000, all of the expired sessions after the first 100 are moved to a new PM_USER_SESSION_ARC table. A large PM_USER_SESSION table causes performance problems, and this is especially problematic when using SHRINE, which frequently starts new sessions.

i2b2 Webclient 

The primary change to the webclient is the addition of the Data Export Manager and Create Data Table plugins. Please note that also legacy plugin subsystem has been removed. The YUI2 library is no longer maintained and has potential security exploits.
